Access Description: The Gaffney prospect is located 57 km south-southwest of Dryden, midway along the southeast shore of Manitou Island of Lower Manitou Lake. Access to the prospect is via motor boat or float plane. The prospect consists of two pits and 26 trenches. (OFR 5731, p. 58-64; 1990)
1904-1905: Mike Nooman sunk a 37.5 feet deep shaft on a quartz vein (Assessment File 52F/07 SW, EE-1, Resident Geologist's Office, Kenora), now filled in but probably at the intersection of Zone C and the northeast trending felsic dike. 1927-1928:Anglo-Canadian Explorers Ltd. opened up 15 trenches uncovering several quartz veins and a zone of sulphides over a length of 900 feet. The claims were allowed to come open in 1928 (Assessment Files, 52F/07 SW, EE-1, Resident Geologist's Office, Kenora). 1928: Frank Gaffney re-staked the claims and organized the Manitou Island syndicate (Assessment File: 52F/07 SW, EE-1, Resident Geologist's Office, Kenora). He collected a number of samples, all of which returned gold values on assay, the best being 2.07 ounces of gold per ton (Assessment File 52F/07 SW, EE-1, Resident Geologist's Office, Kenora). 1931: Claims came open and were restaked by F. Gaffney (Thomson 1933). 1933 - 1934: Property optioned by D.H. Angus. Six holes were diamond drilled for a total footage of 1506 feet (Assessment File 52F/07 SW, E-l, Resident Geologist's Office, Kenora), and thirty samples of the core sent for assay. The best result was 0.29 ounce of gold per ton over 5 feet from hole #1. Resampling and assaying of the trenches was also done. The best chip sample across 5 feet assayed 0.91 ounces of gold per ton in trench #8 (Assessment File 52F/07 SW, CC-1, Resident Geologist's Office, Kenora). A chip sample taken by Thomson (1933) across 12 feet of sulphide material from pit #1 assayed 1.48 ounces gold per ton. 1937: Gaffney Mines Ltd. diamond drilled fourteen holes for a total footage of 1651 feet, to test beneath several trenches to a depth from fifty to one hundred feet. The best assay from core samples yielded 0.54 ounce of gold per ton over 11 feet in hole #12. (Assessment Files 52F/07 SW, E-l, Resident Geologist's Office, Kenora). 1943: The property was optioned by Sylvanite Gold Mines from Frank Gaffney. 1944-1945: Twenty-one holes were diamond drilled by Sylvanite Gold Mines for a total footage of 3100 feet. The deepest holes tested 200 feet below Zones A and B (Assessment Files 52F/07 SW, EE-1, Resident Geologists's Office, Kenora). 1983-1984:Teck Corporation purchased the patented ground. With their joint venture partner Noxe Petroleum Corporation they conducted magnetic, VLF-electromagnetic, and geological surveys, and diamond drilled 21 holes totalling 2,738 m (Assessment Files 52F/07 SW, Y-2, Resident Geologist's Office, Kenora). The best intersection assayed 0.157 ounce of gold per ton over 20.5 m (The Northern Miner, December 14, 1987). 1987:Teck Corporation and San Paulo Exploration Inc. diamond drilled 7 holes (The Northern Miner, May 9, 1988).
